Abstract

The invention discloses a power transformer intelligent on-line state determination system. The system includes a power transformer, a voltage detector, a relay and a temperature sensor. One end of the power transformer is connected to the relay through a wire. The relay is connected to the voltage detector, a temperature sensor and a power-off protector. A voltage range regulator is arranged on one end of the voltage detector. The other end of the voltage range regulator is connected to a voltage alarm through a wire. An excessively high temperature protector is arranged on one end of the temperature sensor. The power transformer intelligent on-line state determination system can detect power change of the power transformer in real time through the voltage detector, and keep the power change within a safe voltage range to prevent dangerous phenomenon caused by overvoltage. The power transformer intelligent on-line state determination system also detects the temperature of the power transformer through the temperature sensor to prevent the temperature of the transformer from being too high. When the power transformer is in a dangerous situation, the power transformer intelligent on-line state determination system alarms in time.

Description

technical field [0001] The invention belongs to the field of power transformers, in particular to an intelligent online state measurement system for power transformers. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. When the input voltage of the power transformer Danger will occur when the ground is unstable, and an intelligent on-line state measurement system for power transformers is designed. Contents of the invention [0003] Aiming at the problems existing in the prior art, the invention provides an intelligent on-line status measurement system of a power transformer. [0004] The present invention is achieved in this way, an intelligent online state measurement system for a power transformer, the intelligent online state measurement system also detects the current of the power transform...
